SPECIFICATION forming part of Letters Patent No. 385,733, dated July 10, 1888.

Application filed August 514, 1887. Serial No. 217,733. (No model.)

T0 on whom it may concern:

Be it known that l, BENJIMAN F. STEWART, a citizen of the United States, and a resident of New Philadelphia, county of Tuscarawas, State of Ohio, have invented a new and useful Improvement in Harvester-l rames, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to improvements in harvestcr-frames; and it consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

Figure 1 is a perspective "iew of a fragment of a harvesterframe illustrating my invention. Fig. 2 is an end elevation of samefrom the grain side.

Similar letters of reference indicate corresponding parts in the accompanying drawings.

As this invention is applicalne to some of the harvester-frames now in use, I will proceed to describe my improvement, referring to other parts of the frame only as conjunctional thereto.

Letter A represents the front and Bthe rear sills; G, the outside and D the inside sills, which in this case are formed of metal pipe; but, if preferred, other forms of metal or material may be substituted.

On the rear end of the sill I) there is pro vided a coupler, E, having a cylinder portion, a, through which the pipe-sill B is passed, a body portion, a, having a female screw cutin the front end thereof, adapted to an annular thread on the end of the sill D. From the body a there is provided a down wardly-projected portion or portions, as a, which terminate in a journal-box, a for the harvester-actuating shaft F. A lug, a projected downwardly from the before mentionedjou rnal-box, is provided, to which the truss-chord G is secured, and a downwardly-projected lug, a,as shown,0n coupler E, to which the rear end of the truss-chord J is secured, its front end being secured to a on the coupler H, and on E a socket, a", for gear shipper i.

The front end of shaft F is supported .in a hanger, K, the upper portion, a of which is semicircular in cross-section and adapted to the circumference of the sill D, and from said upper portion a downwardly-projected pon tion or portions, 0, which terminatein ajournalbox, a, from which a depending arm, (4,, forms a support for the front end of thetruss chord G.

A combined spindle-support and journalbox, L, is provided, peculiarly adapted to a light metal harvester-frame, having an upper portion, 0, semicircular in cross section, adapted to the the circumference of the sill D, a depending arm, I), terminating in ajournalbox, b for the shaft F, and an arm, I). on the lower end of which there is provided a flange, I), by which it is secured to the truss-chord G. On the reverse side there is provided an ontwardly-projectcd spindle, b upon which the pinion b and bevelwheel b are supported, and about which they may be rotated by engagement with the gearwheel M. To further support the truss G, there is a flange, b projected from the gear segmentframe N, to which the truss is seen red, this, together with the upper trusssccured to the top of the segment-frame and to the ends of the sill D, forming a very rigid section of the frame, and ata point where the strain is more severe than at any other.

A rod, d, is suspended between the parts L and E, by which the gear-shipper rod (2 and spring d are held in position, one end of the spring resting against the arm a of coupler E. The energy of thespring is exertedagainstthe shipper-rod d, by which the clutch d is held in engagement with the clutch on pinion, as shown.

Having thus fully described the nature and object of my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of the sill D, alruss, G, a shaft, F, a hanger, K, for supporting the front ends of the shaft F and truss G, a coupler, E, having a cylinder portion to embrace the sill B, a body portion, a, adapted to secure the end of the sill D, a downwardly-projected portion, a journalbox a, and lug a substantially as set forth.

2. The combination of the sill D, a truss, G, ashaft, F, a coupler, E, for supportiugthe rear ends of the shaft F and the truss G, and the hanger K, having a portion, o semicircular in cross-section and located horizontally heneath and adapted to the surface of the sill D,

arms a projected downwardly from the portion a, a jourual-boX, a, supported by the arms and adapted to receive the shaft, and a lug, a forming a support for one end of the truss G, substantially as set forth.

3. The combination, in a harvester-frame, of the sill D, sill B, coupler E, hanger K, and truss-chord G, substantially as set forth.

4. The combination, in a harvester-frame, of the sill D, sill B, coupler E, hanger K,trusschord G, and spindle If, forming a support for a gear-pinion, and the spindle-support L, secured to the sill D and truss G, substantially as set forth.

5. In a harvester frame, the combination of a spindle-support, L, having an upper portion conformed to the sill D and a lower portion conformed to the truss chordG,ajournal-box, b", an outwardly-projected spindle, b, and a shaft, F, mounted in the journal-box 1)", substantially as set forth.

6. In a harvester-frame, the combination, with a sill, D, and the under truss-rod, G, over trussrod, J, means for securing the end of the rod J to the sill, couplers for securing the truss G to the sill D at each end of the former,and a central support to the two trusses and the sill, substantially as set forth.

7. The combination, in a harvester-frame, of the sill D, under truss-rod, Gr, over truss rod, J, means for securing the end of the rod J to the sill, coupler E, connecting the corresponding ends of the truss-chords and sill, hanger K,connecting the under truss-rod with the sill D, spindle-support L, connecting the truss chord G with the sill D, spindle b projected laterally from the spindle support L, and the segment-frame N, forming a central support 'for the truss chords G and J,substantially as set forth.

8. The combination, in a harvester, of the sill D, coupler E, spindle-support L, spindle biprojected laterally therefrom, pinion 1;,and bevel-wheel If, mounted on the spindle, journal-box b, shaft F, mounted therein, bevelwheel (2*, and clutch d, mounted on the shaft, rod (1, spring dfiand gear shipper d in engagement with the clutch d, substantially as set forth.

9. The combinatiou,with the sill D, coupler .E, hanger K, and the shaft F,supported in the coupler E, and spindle support L, of a spindle projected laterally therefrom, gear with clutch-teeth mounted on the shaft F, a gearclutch mounted on the shaft F to engage the clutch-teeth of the gear on the shaft, a rod sus pended between the coupler E and spindlesupport L, a springlocated on the rod, and a gear-clutch shipper in engagement with the clutch, whereby the shipper is pressed by the spring normally in a direction to keep the clutch on the shaft F in engagement with the gear on said shaft, substantially as set forth.

In testimony whereof I have hereunto set my hand this 19th day of August, A. D. 1887.
